The same experimenter can repeat a measurement using the same method and equipment and obtain the same value
Back
Card 17
Front
An experiment can be repeated by a different experimenter using a different method and different apparatus, and still obtain the same results
Back
Card 18
Front
The smallest change in a quantity that causes a visible change in the reading that a measuring instrument records
Back
Card 19
Front
The splitting of a force into its horizontal and vertical components
Back
Card 20
Front
A quantity that only has a magnitude, without an associated direction. Examples include speed, distance and temperature
Back
Card 21
Front
The standard units used in equations. They are: metres, kilograms, seconds, amps, Kelvin and moles
Back
Card 22
Front
A measure of a measurement's resolution. All numbers except zero are counted as a significant figure. When zeros are found immediately after a decimal place, they too are counted.
Back
Card 23
Front
Causes all readings to differ from the true value by a fixed amount. Systematic error cannot be corrected by repeat readings, instead a different technique or apparatus should be used
Back
Card 24
Front
A method of finding the resultant force of two forces. The two forces are joined tip to tail and the result is then the vector that completes the triangle
Back
Card 25
Front
A quantity that has both magnitude and an associated direction. Examples include velocity, displacement and acceleration
